Hello there, i deleted Human01.w3m file to make custom campaign for WC 3 RoC in Ladiks MPQ Editor. I added my custom Human01.w3m file. But it didn't work. Unavaible or missing error then i added orginal Human01.w3m file then I got same missing or unaviable error. What should ı do? when adding file, I didn't use compact or verify files in MPQ Editor.
